Swinburne University of Technology Faculty of Science, Engineering and Technology CVE80004 ADVANCED CONCRETE DESIGN Question 1 (18 marks) The beam below is symmetrically loaded, so it can be designed considering only one half of the beam. For the RIGHT HAND half of the beam only: 1. Draw a layout of major and minor trusses that meet the requirements for a deep beam, using the dimensions shown. 2. Analyse this layout to find the forces in each member. 3. Calculate the minimum widths of the struts. 4. Calculate the dimensions of the node at the right support (do this ONE NODE ONLY) such that it is hydrostatic. fc = 40 MPa, fsy = 500 MPa 2000kN internal lever arm z = 3m beam depth (into the page) is 900mm K 4m 4m Regular Exam Semester 1 2015 Page 1 of 5
